This invention relates to burners, and more especially to improvements in gas burners for use withl baking ovens, stoves retorts and the like. Certain features of the invention are shownl and described in lapplicants corpending application, Serial No. 15,315, filed March 13,1925.

An object of the invention is to provide a burner construction whereby'the volume of mixed fuel and air admitted to the jet openings of the burner maybe independently and selectively controlled.

A further object of the invention consists in arranging a burnercasing and fuel mani fold in sections and coupling or connecting `theadjacent sections in such a manner that fuel can be delivered to the jet openings in the burner directly above the coupling.

Another object comprehends the rovisionof means associated with each o the coupling members for sealing the jointsl g between the sections.

Other objects and advantages will becomeI apparent fromv the following description when taken -in conjunction with the accomy along the line 5 5 of Figure 4.

of another form of the invention. Figure 11 is a view taken substantially along the line 11 11 of Figure 10. l-

Referring to the. drawings and more particularly to' Figures 1, 2 and 3, 10 desig- The su ply `of fuel throu h e vdelivered to the interior of thecasing' from the manifold 12. As the needle valves' 14 are positioned exteriorly-of thecasing 4formed with an exteriorlyI `threaded y in 'natesia burnerfcasing preferably formed'in` sections and having in the top thereof a.

series of uniforml -spaced jet openings 11. The casin whi e shown of substantially cylindrica formin cross section ma, Y as-l sume any desired sha e and has positioned therein a concentrical y formed-fuel or gas manifold tube 12, which preferably is composed of separate sections, but may be ina single piece, and communicates at either end with a fuel supply, not shown. lThe fuel manifold tube'12 is rovided with conical ports 13 diametrica y positioned rela- 11 so as to cause tive to the jet o nings the mixed air an as issuing from the tube 12 to be unifor y distributed to the jet openings 11. l

` u A the rts.13 is prefere ly controlled by n valves 14 which extends through threaded bosses 15 formed the bottom `ofthecasiiig '10,

ufr

Each of the valves 14 is provided at its inner or upper end with' a conical head 16 arranged to extend within'the complementaryv formed openings 13, lwhile the opposite end or base of the valve 14 has akerf or groove 17 arranged to reoeiveany ,suitable tool such as a screw driverlor the likefor regulating the supply ofmixedair and gas 10V and are independently operable itA will be seen that by selectively` the various valves, vthe supply-of-fuel to 1 sections may` be 'varie `without disturbing the flame in other sections. Moreover, the

valves 14 permit the fuel supply to be rev degree without e f` lated. to a jveiunine eter than the interior o f the burner-10 as to form an annular space between' theseI parts, thus a circulation of the fuel 'it' is elivered to the jet Orenmss 11- are preferably connected to andv suppo, by a coupling member or sleeve 18 which' is positioned -witln'nthe 10 and y.: com lementary tge adjacent 19 that ends 0floo Theadjaoent end'of the-burner sections.l e 10 as well as the manifold vtube sec'tionsl lll) ' and a threa the burner casing p, while the abuttin ends ofthe manifold tube sections exten within the coupling 18v and are, supported thereby. v

The jet openings 11 are preferably uniformly spaced apart and extend the ength ofthe burner'casing 10. ln order that the jet openings directly above the coupling members 18 can be supplied with fuel, Athe couplings are each pro-vided with axially. extending grooves 20 arranged on each side of an annular threaded portion 21.0f the couplin these grooves forming fuelpassages w ich deliver the mixed fuel and air tothejet openings 11 above the coupling, thus insurin an even-and uniform flame being emitte throughout the length of the burner when the gas is ignited at any point within the casing.

The annularthreaded portion 21 formed in the sleeve 1 8y is so positioned as .to normally lie between the abutting ends of the sections to provide a packing for sealing the joint between these parts and thus precluding the possibilit of the fuel escaping `from the burner ot erwise than through the jet openings 11. Additionally, the threaded portion 21 ofthis coupling acts asa partition to divide the 'tube 10 into a series' of separateldistribution chambers which may be independently and selectively controlled by the valves 14. 1

v In he modified form .of the invention illustrated in Figures 4 and 5, the fuel or is delivered to the manifold chamber 22 in thecasing 23 through a pipe 'lhe casing `23is preferably of cylindrical form in cross section and has a partition 25 so as to .form a burner chamber 26 above the fuel chamber 22. The chamber 26 has its upper surface formed with uniformly spaced jetv openings 27, and is also divided interiorly into separate compartments *by4 the transn verse partitions 28.

' The fuel or gas lasit delivers to the mani-l fold casing 22 is conducted .to the burner i 'chamber 26 through a series of conical ports 29 in the partition25. The supply offuel passin through each of the ports 29is controlle b a needle valve 30 having at its inner en a complementary formed tapered head 31 arranged to fit in the opening 29 V ed shank which extends thfough a threaded portion formed inthe bottom of the casing 23. The ports 29 are preferably positioned relative to the partitions 28 so that the supply delivered to each comartment vmaybe selectively controlled b e actuation of one of the needle valves In the vform of the inventionshown in Figures 6 and 7, the fuel or gas manifold tube 32 is shown positioned below the burner 'tube 33' and connected thereto at suitable spaced intervals by the threaded nipples 34.

reliance Each of the nipples 34 has a vertical bore 35 .through which the fuel is delivered to the interior of the burner 33; the supplyof fuel being selectively controlled by a needle valve'37 similar in construction and opera- Zo tion to the form of v ves. previously der scribed. The burner tub 33 is divided into separate compartments bythe partitions 38 preferably positioned between the nipplesy 34 and also has jet openings 39 through 75 4 which the mixed gas and air escape.

The form of the invention illustrated in Figures 8 and 9 is somewhat similar to that` shown in lligure l,v and comprises ayburner casing 40 arranged in sections and prefer- 80 ably of cylindricall shape in 'cross section. rlhe fuel manifold tube 41 is also made up Iof sectionsand is provided with conical openings 42 diametrically positioned rela-f tive to the jet openings '43pm the burner -85 casing 40. IThe supply of fuel or gas from the mani-fold tube 4l is exteriorly controlled by means of a threaded bolt 43 which has a, taperedhead' 44 arranged to coact with the conical opening 42 for controlling'the sup- 90 ply of fuel to the `burner casing. The outer end or head 45 of the bolt 43 is of polygonal shape so as to be either manually operated or to receive a wrench or the like for causing the actuation vof the valve. A ,95 locking nut 46 is preferably threaded to the bolt 43 and bears against 'the adjacentA surface of the casing 40 to insure the proper positioning of the valve` A coupling memberor sleeve 47 has an 10 exteriorly threaded surface 48 which vengages a similar formed surface in 'the in-l terior of the casing 40 adjacent the ends of each section.. The coupling 48 is also formed with a, counter-bored portion 49 at 101 each end thereof, so as to form` shoulders that receive the adjacent ends of the gas.- manifold'tube sections 41. The interior of the casing 40 adjacent the ends of each section is formed with .an axially extending-11l recess '49 which is interrupted at the point l where the sections abut one another .byan annular packing ring 50 Yformed of any suitable materia the' lower' portionof the ring 50 being arranged to fit in an a nular. 11@ recess 51 in theinner periphery of the' casing 40.

It will be seen that by' reason of. the axial recess 49 formed in the innerwall of the casing 40, that means are provided for conducting the mixed air and gas to the burners positioned immediately above the coupling 47. rl`he fuel manifold tube 4 1 is preferably y maintained in -a fixed and predetermined position relative tothe burner casing 40 by means ofthe lugs or ribs 51 vwhich radiate fromI the outer wall of the tube'41 and abut against the inner periphe of the tube 40 in the manner as shown in igure 9.

'It is to be understood,of course, thatv the' -13 s lburner casing, as well as thel fuel supply tube, may be composed of any numberof sections which in construction and operation are substantially similar to the forms of the invention previously described.

In Figures andY 11, there is illustrated a further. embodiment of tha invention, in which the burner casing 52 as well as the l fuel delivery tube 53 are vformed in sections,

each section being connected by a coupling or .sleeve 54 which is exteriorly threaded so as to `engage thev threaded rtion of the casing 52. The bore 55 oft e coupling 54 is providedgat each end with anKenlarged counter-bored portion that forms the shoulders '56 which receive theadjacent ends of the fuel tube 53. The interior o f the casing 52 adjacent the ends thereof has an axially extending peripheral groove 57 which is interrupted Vat the point of contact of the adjacent ends of the sections of the casing 52 by an enlarged annular rib 58which acts as.

a packin or seal to prevent the escape of fuel at t e point of contact of the burner sections. f The upper surface of the casing 52 has the jet openings 59 positioned so as to uniformly distribute the lflame throughout the length of the burner.

The supply of mixed air and gas from the manifold tube 53 is delivered to the interior vof the casing 52, and conducted to the jet openings 59, through' o'rts 60, preferably formed'in the bottom the tube 53, each of the ports having an exteriorly threaded',

bushing or sleeve 60. which engages in the threaded openings formed inthe bottom of the casing -52 and tube;53. The inward movement of the bushing 60 is limited by a flange 61 arranged to abut against the outer Q casing`52 throu h the radial surfaceof the casing 52.` IThe inner end of the' bushing'60 is formed with a vertical orifice 62 which delivers to a chamber 63 that ,communicates 'withtlre interior of the ports 64. A valve 65 contro the suppl opening 62' and has a threa ed shan portion 66 which-terminates in an enlarged head67, saidgliead bei positioned below lthecasing 'andoutsidext ereof so as to be "tool, to controlthe supply of suitable casing. `A lock nut 68, `is threaded tothe manually actuated or operated by shank-66 and engages the flange 61 of the,` wbushing `60 so as to maintain the valve in any ,predetermined position- In 'this form of the -invention,-'it will be observed that the mixture-of air and gas isconducted through the ports 62 and openings-64i1i'to'the 1nteriornof the. casing 52 where it is distributed to all the jet openings 59 including those ,above the coupling 54, the latter being supplied throughthe Ia'irial grooves 57 1n the casing 52.v
